TasPort's Kevin Moore says an extra 10 visits have already been booked for next summer.

He says the new $7 million cruise ship terminal in Hobart is helping to attract more.

"It's actually dedicated to cruise and also Antarctic activities so, in terms of the facilities being offered to this growing number of passengers, they're going to get better service and better amenity for when they do visit Hobart," he said.

Will Barbour from Tasmanian Air Adventures says flights sometimes treble when the cruise ships are in.

"For Hobart this cruise ship business is really important," he said.

"It brings a number of people from all over the world reliably each summer and the flow on effect along the Hobart waterfront is very, very important."

The Tourism Council's Like Martin wants to see more ports upgraded to allow tourists to experience Coles Bay and other areas.

"Port Arthur's now expanding their jetty to cater for a bigger ship and then (we should) obviously look at opportunities around the east coast and the north-west."
